Pretty cool: an alpha image of Android 4.2 from the leaked LG Nexus device includes SELinux. "According to the layout xml, SELinux will have a status readout tacked-on to the current About Phone screen. It will now list 'SELinux Status' at the very bottom, right under 'Kernel version' and 'Build Number'. If you're wondering why there are 3 options and not just 'on' and 'off', 'Permissive' is a logging mode, which will tell you when it would have blocked something, but won't actually block things. The other key piece of information to get from the string file is that this is an optional mode, don't go around saying that Google is shutting down root functionality or anything. This is for security conscious enterprise and government-types and probably won't be enabled on consumer phones."
